Title: Production of concentrated stable solutions of dimethylaminophenyldimethylpyrazolone
IPC: A61K47/22
Filed: 1952-06-10
Abstract: Stable aqueous solutions are produced by a process in which dimethylaminophenyldimethylpyrazolone and phenyldimethylpyrazolone are dissolved in water to form an aqueous solution containing at least 5 gm. dimethylaminophenyldimethylpyrazolone per 100 cc., the solution is filled into ampoules, and the ampoules are heated.  The step of heating the solution in the ampoules stabilizes the solutions against crystallization.  Preferably 0.8 to 1.2 parts by weight of phenyldimethylpyrazolone are employed to 1 part by weight of dimethylaminophenyldimethylpyrazolone.  In examples of the process solutions are prepared (a) containing 15 parts by weight of each pyrazolone derivative made up to 100 parts by volume with water; (b) containing 20 parts of dimethylaminophenyldimethylpyrazolone, and 24 parts of phenyldimethylpyrazolone dissolved in 100 parts of water. Other medicaments, e.g codeine salts, calcium salts or p-aminobenzoyldiethylaminoethanol or its hydrochloride, can be added to the solutions.  Specification 9916/40 (as open to inspection under Sect. 91) is referred to.ALSO:Stable aqueous solutions are produced by a process in which dimethylaminophenyl-dimethylpyrazolone and phenyldimethylpyrazolone are dissolved in water to form aqueous solutions containing at least 5 gm dimethylaminophenyldimethylpyrazolone per 100 ccs., the solution is filled into ampules, and the ampules are heated.

Title: Improvements relating to de-lidders for removing lids from pans
Inventor: ROBINSON WALTER
IPC: A21B3/18
Filed: 1970-04-02
Abstract: 1,274,388. Delidding bakery pans. SPOONER FOOD MACHINERY ENG. CO. Ltd. 19 April, 1971 [2 April, 1970], No. 15560/70. Heading A2A. The height of a bakery pan delidding head is adjusted automatically by sensing means responsive to the height of the pans, with their lids, as they approach the delidding head. In one embodiment, the delidding head 74 includes a pair of ramps 14 for engagement beneath laterally extending rims on the lids so that as the pans are carried leftwardly on a conveyor 70 towards a depanner, e.g. a suction depanner (not shown), the lids are caused to pass up the ramps on to a conveyor 15. The height of the pans is sensed by a feeler 102 on a spindle 103 mounted in a head 104, rotation of the spindle 103 operating a potentiometer which unbalances a bridge circuit to cause an electric motor 100 to raise or lower the head 74 through reduction gearing 101 and a screw jack 98. The head 74, which includes vertical members. 94 guided in a frame 90 by rollers 95, 96, is connected to a feedback chain 107 whereby the head 104 is adjusted in correspondence with the head 74 to cause the potentiometer to rebalance the bridge. The control circuitry for the motor 100 may be such that upward adjustment is effected quicker than downward adjustment, and the feeler 102 may operate a switch to limit the extent of the downward adjustment. Photo-electric cells may be used instead of the feeler, and a hydraulic jack instead of the motor 100 and screw jack. The delidding head may comprise wheels fitted with magnets to remove the lids instead of the ramps 14. In another embodiment, the feeler is mounted on an extension of the delidding head and operates a valve which controls a hydraulic jack adjusting the head.
